Not real clear on the question specifically but maybe this will help:
Some (maybe most) do not have access holes in the back so you must thread the strings from the front (the long end will be accessible from the base). Tie the knot in the usual way.
Most also use guitar machines instead of pegs; just tune it up as you would a guitar.
You will of course have to have the correct string sizes (and excess lengths if threading from the front).
